Benefits of technology

The patent text describes a seat assembly with various types of arm and leg restraints. The seat assembly includes a seat portion, back portion, and arm restraint assembly or leg restraint assembly. The arm restraint assembly has a rotating bar that can be moved from a stowed position to a deployed position to restrain the occupant. The leg restraint assembly has an extension bar that can be moved from a stowed position to a deployed position to restrain the occupant. These seat assemblies provide better safety for the occupant in the event of a collision or other emergency situation.

Problems solved by technology

Due to their orientation, some side-facing passenger seats may not provide sufficient occupant restraint during a crash.
However, airbag systems add significant weight and cost, diminish aesthetics of seat belts, and add a large certification burden to the installer.
Active systems also increase cost of life cycle operation and maintenance.

Embodiment Construction

[0017]Described herein are restraint systems for side-facing vehicle seats. The system includes a first structure to restrain an occupant's torso and a second structure to restrain an occupant's legs. The first structure deploys on the forward side of the occupant's shoulder / arm, and is deployed in addition to safety belts during taxi, takeoff, and landing. The first structure is hidden within the top of the seat back and pops up from the seat back and rotates into place manually by the occupant of the seat. The second structure deploys on the forward side of the occupant's legs and is hidden within a lower portion of the seat. The second structure is withdrawn from the seat and rotates into place manually by the occupant. The first structure sits mid-arm on the occupant and the second structure sits mid-leg on the occupant. As such, the restraint system closely restrains the occupant to the seat structure during a crash, thereby preventing potential injury.

Abstract

In one aspect, a side-facing seat assembly is provided. The seat assembly includes a seat portion, a back portion having an upper surface extending along the width of the back portion, and an arm restraint assembly coupled to the back portion. The arm restraint assembly includes a rotating bar rotatable between a stowed position oriented with the back portion upper surface and a deployed position. In the deployed position the rotating bar extends from the back portion and facilitates restraining an occupant seated in the seat assembly. The seat assembly further includes a leg restraint assembly coupled to the seat portion. The leg restraint assembly includes an extension bar extendable between a stowed position oriented with the seat portion and a deployed position. In the deployed position the extension bar extends from the seat portion and facilitates restraining an occupant seated in the seat assembly.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. provisional patent application Ser. No. 62 / 027,452, filed Jul. 22, 2014, the entire contents of which are incorporated herein by reference.BACKGROUND[0002]The subject matter disclosed herein generally relates to restraint systems for vehicles, and more specifically, to restraint systems for side-facing aircraft seats.[0003]Some aircraft may include seating devices referred to as divans to accommodate one or more passengers within the aircraft. Divans are generally couch-like structures where one or more passengers can comfortably sit in a less formal, customized environment different from that typically utilized in commercial, passenger aircraft. The interior of such aircraft may include individual seats and divans installed in the aircraft in a side-facing orientation. Due to their orientation, some side-facing passenger seats may not provide sufficient occupant restraint during a crash. Known ...
